Is there a minimally viable version of it that you could start selling?

From what I read, it sounds way too "in the weeds" to really be a marketable good/service.

Otherwise, kids are rough. I'm not much older than you. I realize probably every day past 30 (give or take) I'm moving slower, and kids can be outright chaos demons. There's also the fact of wanting to be established with a corporation to some extent before you ask for time off to have a kid. There's a HUGE amount of corporate knowledge and wisdom to know, but the minimal is you may be outright unable to take time off during any probationary period at a new job. The probation period could be anywhere from 0 days (unlikely), 90 days (common), to a year (not unheard of). If your "have a kid" deadline is 2 years from now and you probably need to have a decent professional relationship with an employer for a year before having the kid, the time to get hired is in the next year. I think that means it's time to get serious with applying for work as a search can take considerable time. Probably time to get "desperate" about finding work around 9 months from now, as a guestimate?
